Signal emission warning device based on magnetic induction system to monitor forklift shovel tooth shedding

Abstract

The invention provides a signal emission warning device for monitoring falling off of forklift form-relieved teeth on the basis of a magnetic induction system. The signal emission warning device comprises a trigger circuit loop formed by a power source, a signal generator and a magnetic induction switch. The signal generator is connected with a signal emission end. The magnetic induction switch comprises two contactors on the trigger circuit loop, a first electromagnetic sheet and a second electromagnetic sheet, wherein the contactors do not make contact with each other, and the second electromagnetic sheet is located between the contactors and the first electromagnetic sheet. When the form-relieved teeth are connected with a bucket normally, the second electromagnetic sheet is attracted by the first electromagnetic sheet, so that the trigger circuit loop is disconnected. When the form-relieved teeth and the bucket generate relative displacement or rotation, the contact area between the second electromagnetic sheet and the first electromagnetic sheet is reduced, as a result, mutual magnetic force is reduced, thus, the second electromagnetic sheet is separated from the first electromagnetic sheet and attracted by the two contactors so that the trigger circuit loop can be communicated, and the signal generator generates signals to be sent out through the signal emission end. The device is low in cost, small and exquisite in design, easy to install and capable of discovering falling off of the form-relieved teeth in time.

Description

technical field [0001] The invention relates to the field of monitoring the shovel teeth slipping off of a forklift, in particular to a signal emission warning device for monitoring the shovel teeth falling off of a forklift based on a magnetic induction system. Background technique [0002] When the forklift is loading ore, the shovel teeth on the bucket often fall off due to the broken bolt. When the forklift is loading ore, the fallen shovel teeth will be loaded into the mine car together with the ore. If it cannot be found in time, the fallen shovel teeth will be unloaded into the ore crusher together with the ore. The shovel teeth are very hard. Once they enter the crusher, the crusher will be stuck, causing damage to the roller teeth of the crusher and the deceleration system, resulting in huge economic losses. [0003] In the prior art, industrial cameras are used to monitor the condition of the shovel teeth. Due to the influence of weather conditions, air quality, ...

AI Technical Summary

Problems solved by technology

The shovel teeth are very hard. Once they enter the crusher, the crusher will be stuck, causing damage to the crusher roller teeth and deceleration system, resulting in huge economic losses.

[0003] In the prior art, industrial cameras are used to monitor the condition of the shovel teeth. Due to the influence of weather conditions, air quality, and vibrations during construction, the monitoring results are not ideal.
